Abstract

When a patient is fitted with an external gastrostomy connection to the stomach, ingested food can be removed through the gastrostomy connection using a pump-based or siphon-based system to achieve weight loss. The process of removing ingested food can be improved by alternating the infusion of liquid into the stomach with the removal of material from the stomach. Optionally, stomach acid may be captured and returned to the stomach. Optionally, nutritional supplements or medicines may be added to the infused liquid. Optionally, a flush mount connectorized system with a built in valve may be used to simplify the interface with the gastrostomy hardware that remains installed in the patient. Optionally, the system may be configured to disable itself from further use after a triggering event (e.g., the passage of time or a predetermined number of uses) has occurred.

Claims

1. A method of removing ingested food from a patient'"'"'s stomach via a gastrostomy tube that passes through the patient'"'"'s abdominal wall into the patient'"'"'s stomach, the method comprising the steps of:

providing an apparatus for siphoning or pumping ingested food out of the patient'"'"'s stomach via the gastrostomy tube; and

limiting the number of times that the siphoning or pumping operation can be performed by the apparatus.

2. The method of claim 1, wherein the number of times that the siphoning or pumping operation can be performed is limited based on elapsed time from a first use.

3. The method of claim 1, wherein the number of times that the siphoning or pumping operation can be performed is limited based on how many times siphoning or pumping of food has been performed.

4. The method of claim 1, wherein the number of times that the siphoning or pumping operation can be performed is limited based on how many times the apparatus has been connected to the gastrostomy tube.

5. The method of claim 1, wherein the number of times that the siphoning or pumping operation can be performed is limited based on the volume of matter that has been extracted from the patient'"'"'s stomach.

6. The method of claim 1, further comprising the step of:

infusing liquid into the patient'"'"'s stomach via the gastrostomy tube, wherein the infusing step is performed in alternation with the siphoning or pumping.

7. An apparatus for removing food from a patient'"'"'s stomach via a gastrostomy tube that passes through the patient'"'"'s abdominal wall into the patient'"'"'s stomach, the apparatus comprising:

a connector configured to connect to a proximal end of the gastrostomy tube with a fluid-tight connection; and

a first fluid path provided between the connector and a drain port, configured to permit, for a limited number of times only, siphoning or pumping food from the patient'"'"'s stomach out to the drain port.

8. The apparatus of claim 7, wherein the number of times that the siphoning or pumping can be performed is limited based on elapsed time from a first use.

9. The apparatus of claim 7, wherein the number of times that the siphoning or pumping can be performed is limited based on how many times siphoning or pumping of food has been performed.

10. The apparatus of claim 7, wherein the number of times that the siphoning or pumping can be performed is limited based on how many times the apparatus has been connected to the gastrostomy tube.

11. The apparatus of claim 7, wherein the number of times that the siphoning or pumping can be performed is limited based on the volume of matter that has been extracted from the patient'"'"'s stomach.

12. The apparatus of claim 7, further comprising:

a reservoir for holding liquid to be infused into the patient'"'"'s stomach;

a second fluid path from the reservoir to the connector, configured to permit infusion of the liquid in the reservoir into the patient'"'"'s stomach; and

a fluid circuit configured to alternately (a) open the first fluid path during a first interval of time to permit siphoning or pumping food from the patient'"'"'s stomach and (b) open the second fluid path during a second interval of time to permit infusion of the liquid in the reservoir into the patient'"'"'s stomach.
